What is Sanitary safety valve?
Jun 18, 2018

Sanitary safety valves are used in food, beverage, dairy products, pharmaceuticals, beer and other industries.

Introduction: Safety valves are important safety accessories for boilers, pressure vessels and other pressurized equipment and should be checked frequently to make them safe and reliable.

Role of safety valve: Sanitary safety valve plays a role of safety protection in the system. When the system pressure exceeds the specified value, the sanitary-level safety valve is opened, and part of the gas/fluid in the system is discharged into the atmosphere/outside of the pipeline so that the system pressure does not exceed the allowable value, thereby ensuring that the system does not cause accidents due to high pressure.

          Technical Parameters

         Connection form: welded, quick-mounted, threaded

         Material: Made of SUS304, SUS316L Diameter: DN25

         Applicable to recovery and degassing of CO2 gas in the fermenter and maintaining stable tank pressure

         Classification: There are two main types of safety valve structures: spring type and lever type. Spring type refers to the valve and valve seat seal spring force. Leverage is based on the leverage and weight of the force. With the need for large capacity, there is also a pulse-type safety valve, also called a pilot-type safety valve, composed of a main safety valve and an auxiliary valve. When the medium pressure in the pipeline exceeds the specified pressure value, the auxiliary valve is opened first, the medium enters the main safety valve along the conduit, and the main safety valve is opened, so that the increased medium pressure is reduced.

          The discharge of sanitary safety valve is determined by the valve seat diameter and the opening height of the valve disc. It can also be divided into two types: The micro opening height is the valve seat inner diameter (1/15) to (1/20), all Kai-style is (1/3) ~ (1/4).

         In addition, with the different requirements for use, there are closed and non-closed. The closed type, ie the discharged medium, is not leaked and is discharged along the specified outlet. It is generally used for toxic and corrosive media.
